I once had a girl who I fucked in the mouth who wasn't ready and it knocked out her teeth and thence she has had to smile like Alice here. Maybe Alice has no teeth. Oh well, cuts down on the tooth drag.

Alice may have gone down the rabbit hole more than once, but she is a delight to the eyes, nonetheless.
I agree with Mongo that she is holding back a little perhaps to entice us to look further. Those, who want her to give them a good blow, should know that she has a fine set of choppers see below.

@Mongo, wasn't the head better without your girls dentures anyway? I would think she would have offered to take her choppers out before sucking your snausage as a polite gesture. Maybe she had some senility going on? (That would explain wanting to go down on you in the first place. Unless you Bill Cosby'd her.)
